"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

"We just had a roof done by home genius exteriors. We started with Justine at our door setting up an appointment for someone to tell us about the process. The next day Dan came and explained how the company works. He even crawled around our attic to show us the damage. Within 2 days our roof was in the process of being installed. Zach the project manager stopped by 3 times during that day to see how the work was being done. What a professional company. Everyone that we spoke to or met was very professional and friendly,. I would highly recommend this company for installing a roof."

"I researched and found Devon and his company were very well reviewed and he was great on the phone. We have a 1904 home with vermiculite and old batting for insulation in the attic. Devon came out to the house and was planning to do the removal of the old insulation but the vermiculite was determined to have asbestos, so we had everything in the attic remediated. Devon told me about the ZAI Trust and I was able to submit a claim for the abatement and reinsulation. Devon also discovered that a small roof off the kitchen/dining area was uninsulated as well as the dormer roof and the ensuite below it. We had to reschedule suddenly due to Mum being admitted to the ER, and Devon had no issue with this at all, and was very supportive. Devon and his team did an amazing job! What great people! They worked so hard and the spackling job to cover the holes was terrific. We just primed and painted. Devon will be back here to review the insulation status in the rest of the home, as the old foam insulation may need to be supplemented. I'd hire Go Go Green Insulation in a heartbeat and have already recommended them to a couple of neighbours. Old home, apt. or new build, these guys are the BEST!"

Insulation FAQs, answered by experts

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.
